简介：The air freshener is more useful than media filters. Charged media filters lose their charge frequently and become less effective after every use, requiring a filter replacement to regain efficiency. In fact, some charged media filters emit ozone, a dangerous lung irritant that pollutes your air and should be avoided by allergy and asthma sufferers. Compared with the air freshener made from water beads, some types of charged media filters like air purifiers offer optional smoke, odor, and gas removal filters. Known for their stylish and sleek design, air purifiers offer low energy consumption and easy-to-replace filters. With either a Smoke stop filter or a particle and gas filter, air purifiers remove 99.97% of particles at 0.1 micron, and they don't emit ozone. In addition to charged media filters, electrostatic devices be used to safely clean air and neutralize odors. As air is pushed through many static prone fibers, electronic cells charge airborne particles and capture them inside of collector plates. As electrostatic precipitators don't require filters, you don't have to worry about replacing the filters. Simply wash the collector plates and insert them back into the air purifier for fresh, clean air. The air freshener is the most common material to deal with the odor and its ingredients could be used to make cold hot pack as well.
